To all may concern:

Be it known that. I, Fnnonrcn C. Mam, a

citizen of the United States, residing' at Succasunna', in the county ofMorris, State of New Jersey, have invented certain new and usefulImprovements in Self-Weighing Bald I- do hereby declare the fol- .tionofcthe invention, such as will enable others'in the art to which itappertain'shtormake and use the same.

Thi's' invention relates to improvements in scales-and particularly toattachments for beam -er; platform scales.

Theprincipal ob ectof the invention is to provide a simple and novelindicating attachme'ntwhich is automatic in-its action to,in-

.dicate the weights of-articles placed on the platformjyithoutathe useIof-the ordinary Another. fject resides in the peculiar construction andarrangement of the member which'engagejs' with; the beam of the scale.

Other ob ectsand advantages will be apparentfmm thefoHoWing descriptionwhen taken in connwticn with the accompanying drawing. 1
